Health care in America: what Constitution?

Both parties to this contract, by entering into it, are giving up their constitutional right to have any such dispute decided in a court of law before a jury, and instead are accepting the use of arbitration. Both parties also agree to give up any right to pursue on a class basis any claim or controversy against the other. —€”from Blue Cross HMO Exclusions and Limitations

OK, I can appreciate that they are attempting to protect themselves from the «ever greater litigiousness» purportedly at work in the United States. Who doesn’t want to cover their asses? But you gotta love it: if you want to survive the gunshot you’ll inevitably receive as a citizen of this gun-crazy land (and yes, I believe in the Constitution and the right to bear arms; the «right to» and the «intelligence of the decision to» are not the same thing) you must sign away your constitutional right to have your dispute settled by a court of law. I guess «Life, Liberty and the Pursuit of Happiness» are unalienable, but the rest of the Constitution is negotiable?
